Description
Technical Field
The invention relates to a three-dimensional shock insulation (vibration) system for buildings.
Background
At present, a shock insulation (vibration) support of a building mainly comprises a natural rubber shock insulation support, a lead core rubber shock insulation support, a high damping rubber shock insulation support and a sliding support. The traditional vibration isolation support usually aims at solving the problem of horizontal earthquake, and can not well isolate vertical earthquake, so that the structure is easily damaged and destroyed. Although partial three-dimensional shock insulation support can better solve small-amplitude vibration at present, large-amplitude seismic vibration is not met by a better shock insulation structure system.
Within the field, vibration isolation refers to isolation from seismic and vibration pollution in the environment. The invention can start isolation action to earthquake and vibration.
Disadvantages/drawbacks of conventional techniques: to date, there have been some vertical isolation bearing patents on the market, but most solution is the little vertical deformation problem of similar subway vibration isolation, and normal vertical isolation bearing can't have great vertical deformation to in the earthquake effect, vertical shock insulation effect is unsatisfactory, still can enlarge even. Also in the possible case of large displacement deformations, the support can undergo a large deformation causing the structure to overturn and sway.
The adopted shock insulation technology is an effective method for enhancing the earthquake resistance of a house, but most of the widely applied shock insulation technologies at present do not have the function of isolating strong vertical earthquake motion. Experience shows that strong vertical seismic motion can be generated near the epicenter and the earthquake-induced fault, seismic disasters caused by huge vertical seismic components cannot be ignored, and it is very necessary to further control the structural three-dimensional seismic response by adopting effective measures.
As most of three-dimensional isolation analysis in the current market takes a single three-dimensional isolation support as a research object, the problems of swinging and support cooperative work caused by the single three-dimensional support are not well solved.
